To all whom. it may concern.

Be it known that I, GEORGE WV. DONNING, a citizen of the United States,residing at Stamford, in the county of F airfield and State ofConnecticut, have invented certain new and useful Improvements, in Type\Vriters, of which the following is a specification, reference being hadtherein to the ac eompanying drawing.

This invention relates to typewriters and, particularly, to structuresemployed in conjunction therewith for supporting and positioningmanifolding material in relation to the platen forming a part of saidtypewriter.

The object of the invention is, primarily, to provide a. manifoldingelement adapted to be supported and positioned, at the will of theoperator, in relation to the platen, and to combine therewith simple andeasilyananipulatcd means for actuating said ma ni fu filll"-0l'l]10lltwhenever. necessarywhether it on for the purpose of presenting areiativclv ditferent surface in position for operation, or for bodilychanging its position in relation to the platen.

in a more specific aspect, the invention includes carl'ion -supportingmeans sustained by parts of the machine other than thecarriagesupporting rails forming a part of said machine.

The present case is a true divisionof an application filed by me June6th, 1899, Serial No. 719,623, for improvements in typewriters, andwhich has now eventuated in Patent No. 970,195, dated September 13th,1910, and is directed to subject-matter expressly carved out of saidapplication, In that case, the subject-matter comprchends, among otherstructure, manifolding-devices in which the carbon-sustaining devicesare supported, particularly, in relation to or on thecarriage-supporting rails or'guides.

As before stated, t-he-subject-matter of the.

present case has relation to manifoldingdevices in which thesupporting-structures therer'or are distinct from said rails or guides,in the sense that they are independent thereof. One embodiment of suchstructure contemplates the provision of supporting-devices carried by ordisposed adjacent to the 'laten'of the machine. In tieaccompanyingdrawings, I have illustrated some of the embodiments of my inventionand, in said drawings: Figure 1 is a view in perspective showing oneform of ty )ewriting-machine in which my invention is embodied; Fig. 2isa similar View of one form of platen detached from the machine, and towhich is attached a form of device for supporting and positioning amanifolding-elenient; Fig. 3 is a'similar view of one form of platenwith which is mounted a different form of device-for supporting andpositioning a manitoldirig-element; Fig. 4- is a similar view, showingthe forms of n'ianifolding-dcviccs shown in Figs. 2 and 3 combined,whereby a. plurality of copies may be produced at one writing; and Fig.5 is .a similar view of a modified form of structure, wherein thecarbon-supporting and p0- sitioning device is independent of the platenand track-frame and is shittablc over the latter and t-iltablerelatively thereto.

In these drawings: The numeral 1 designates a platen which, in thisinstance, is of the so-called flat-platen form. It may, if desired, bet-iltable and, to this end, would be pivoted at one edge, as at 2.

Underlying the platen is a supportingstructure 3 which, in someinstances, (as in the present), is adapted to sustain a trackframe 4upon which is mounted a printingmecha'nism 5. The track-frame, in thisinstance, is shown, by way of example, as tiltable, and, to this fond ishinged, as at 4.

In Fig. 1 a taveling book-supporting structure 6 is shown, booksustainedthereby is shown as extending across the platen;

As illustrated in Fig. 1 and, on a larger scale, in Fig. 2, the platen 1is provided with carbon-carrying members, spindles, or rolls 8, 8, rotatably mounted in brackets 9, 9, beneath the forward and rear ends of thplaten. Each of said carrying-members 8 18 provided with a knurled headOr portion 10, respectively, and whereby said members may be rotated bythe operator. It

will be understood that carbon, or any other and a page 7 ot' theappropriate form of inanifolding material,

or sheet over the operative surface of the. platen. By these means, aswill be readily understood, the carbon-sheet or other form ofmanifold-ing-element may be supported and positioned over the platen. Tofacili-- tate these operations, the platen may be provided, adjacent thecarrying-members and parallel therewith, with elongated slots orapertures 11, 11, through .which the manifolding-sheet or ribbonreadilypasses.

Iii-Fig. 3, l have shown another form or. manifoldmg-device. 12 which 15adapted to support and position a manifolding-element or ribbon' overthe operative surface of the platen: In this instance, the devicecomprises a frame 13 to which is secured the sheet .or ribbon ofmanitolding-material. Connecting with the frame is an actuatingmechanism1+1 wherebyit may be moved (and, with it, the manifolding-element) inrelation to the platen.

In Fig. 4, I have shown both of the described forms ofmanifoiding-deviees operatively combined; that is to say, therotatable'form of carbon-carriers of Fig. 2 are shbwn as supporting asheet'to overlie the platen, and the frame-form of Fig. 3 is shown assupporting its manifolding-element so as to overlie the first-mentionedmanitolding-element. By these means, as is obvious, a plurality ofcopies may beproduccd simultaneously: The lower manifolding' elementmay, in this instance, rest upon the upper surface of the'platen; thenasheet or book-page may be laid thereover; a second sheet or page wouldthenbe arranged to overlie this; and, then, the manifolding-ele ment orribbon carried by theframe would be interposed between said second sheetand a third sheet against which the, type would strike and print. If themanifolding-element in each instance isv an inked fabric, the copieswould all be ribbon or original copies. It a further copy is desired, I'

would provide a third term of manifoldingdevice 15,.in the form of a.frame 16, suitably fniounted adjacent to, but independently of theplaten, as shown in Fig. It is adapted to position its sheet across theplaten-- in this instance, at right-angles to the sheet. carried by theframe 12. i

To confine the Worksheets or a manifold ing-element upon the laten, oneor more clamping-devices 17, 1% mav be provided ass-shown in Fig. 4. Itwill be understood that the frame 12 may similarly be utilized a.tiltable platen is employpd, it would, of

course, be disposed independently of the platen and so arranged that itcould conveniently be positioned in operative relation to i the platen.

In Fig. 5, I have shown still another form of manifolding-device 18which, in this instance, is a frame 19 pivotally and slidably mounted ona rod 20 journaled in upstanding lugs 21, 21, carried by a supportingmember 22. In this example or embodiment, it Will be seen that the saidframe may be tilted away from the platen, and, also, shifted thereover.By this means, the manifolding-element carried by the frame may be p0sition-ed in relation to the platen in'a plurality of directions. Theframe carries spindles, 23, 23, and the sheet may pass through elongatedslots 24 formed in said frame adjacentto said spindles.

By the several elements disclosed, where the platen-supported spindles8, 8 carry stationery, in the form of a work-sheet, etc., thepositioning-frame may carry a inanifolding-element. Or, theplaten-supported spindles would carry the work-sheet, as mentioned, theframe carry the manifoldingr-element, and the clamp-devices 17 beutilized to hold'down, at one edge of the 'platen,'one or more sheets.including carbon sheets, etc, and by which several means, also, theclamps and said carbon-homing frame could be utilized to hold down thework at a plurality of points, when necesary. lVhere the platen-spindlesare thus employed to support a work-sheet, and the frame (that one, forinstance, which is operated by foot-mechanism, as already described),the extensions 13, 13, could underly the carbon so as to raise it awayfrom the platen when the work is released by the body-portimi 13thereof.

In still another aspect of the invention,

the platen-supported spindles would carrv.

the manifolding-element, and the several clamping-devices (including theclamps 17, the frame 13, etc.) would be utilized to confine thework-sheet.

In a further aspect, the clamp 17 could be utilized to hold one or moresheets of carbon, and the carboncarrying-frame made further useful tohold the work-sheet or sheets.

Other obvious changes could similarly be made and. yet be within thespirit of my invention.

Having thus fully described my invention, its construction and its modeof operation, what- I claim and desire to secure by Letters-Patent is:
